The method also comprises the steps of introducing a fluidization agent at the one or more temporary urinals, guiding the liquid waste and the fluidization agent from the one or more temporary urinals to the at least one holding tank via the waste piping system, wherein the fluidization agent prevent precipitation of solids from the liquid waste in the waste piping.

BACKGROUND

Generally, disposal of human waste in construction sites is conducted by locating portable toilets on the ground level of a building under construction. In a multi-level building under construction such as high-rise buildings or the like, ground level portable toilets are inconvenient and difficult to reach for those workers at above ground floor levels. Ceilings on multi-level buildings under construction prevent cranes from placing portable toilets on above-ground floor levels. Thus, unsanitary conditions frequently result in construction sites from workers located in these above-ground floor levels. Such unsanitary conditions commonly found in multi-level construction sites are containers of liquid human waste, liquid human waste lying on the floor and other areas of a building under construction, and the associated odor with these open pools and containers of liquid human waste. Thus, there exists a need in the art to provide sanitary conditions and dispose of liquid human waste in a multi-level building under construction.

It is therefore an object of the disclosed subject matter to obviate the deficiencies of the prior art by presenting a novel temporary urinal comprising a basin, a drain, and a splash guard wherein an upper portion of the temporary urinal comprises an attachment device adapted for attaching the temporary urinal to a wall system.

It is another object of the disclosed subject matter to present a novel temporary liquid waste system for an above ground level floor in a building under construction without permanent plumbing fixtures. The temporary liquid waste system comprises one or more urinals located on the above ground level floor, at least one holding tank located at or below ground level, and a liquid waste piping system extending from each of the one or more urinals to the at least one holding tank whereby the one or more urinals and the at least one holding tank are disparately located.

It is still another object of the disclosed subject matter to present a novel method for temporary sanitary disposal of human liquid waste in a building under construction on a level above ground level with a ceiling and prior to the installation of permanent plumbing fixtures. The method comprises the steps of providing one or more temporary urinals on the level, providing at least one holding tank capable of accumulating liquid waste at or below ground level, and providing liquid waste piping between each of the one or more temporary urinals and the at least one holding tank. The method also comprises the steps of introducing a fluidization agent at the one or more temporary urinals, guiding the liquid waste and the fluidization agent from the one or more temporary urinals to the at least one holding tank via the waste piping system, wherein the fluidization agent prevent precipitation of solids from the liquid waste in the waste piping.

It is yet another object of the disclosed subject matter to present a novel temporary liquid waste system for an above ground level floor in a building under construction without permanent plumbing fixtures. The system comprises one or more temporary urinals located on the above ground level floor, a sewer interface located at or below ground level, a connection device, a trapless liquid waste piping system extending from the above ground floor to the sewer interface and adapted to receive permanent toilet fixtures, and a connection device extending between the one or more temporary urinals and the trapless liquid waste piping system.

It is also an object of the disclosed subject matter to present a novel method to reduce the proliferation of containers of human urine on interior levels of a multilevel building during the construction of the building and prior to installation of permanent plumbing fixtures where the interior levels are above ground level. The method comprises the steps of providing one or more temporary urinals on one of the interior levels, providing a waste collection interface capable of disposing liquid waste at or below ground level, and providing liquid waste piping between each of the one or more temporary urinals and the waste collection interface. The method also comprises the steps of introducing fluidization agent at the one or more temporary urinals, guiding the liquid waste and the fluidization agent from the one or more temporary urinals to the waste collection interface via the waste piping system, and removing the liquid waste and the fluidization agent from waste collection interface.

These objects and other advantages of the disclosed subject matter will be readily apparent to one skilled in the art to which the disclosure pertains from a perusal or the claims, the appended drawings, and the following detailed description of the preferred embodiments.
